BiasAddBackprop
BiasAddBackprop#
Versioned name: BiasAddBackprop-1
Category: Arithmetic
Short description: Computes the gradients on the “bias” tensor for add bias operator.
Detailed description:
This op accumulates all the values from output_delta into the channel dimension, the axis depends on the layout of input tensor.
Attributes:
data_format
Description: data_format denotes the data format of the input.
Range of values: NXC or NCX (X means HW for 2D, DHW for 3D)
Type: string
Default value: NXC
Required: no
Inputs:
1:
output_delta
- the gradient tensor with respect to the output. Required.Type: T
Outputs:
1:
bias_delta
- the gradient tensor with respect to bias.Type: T
Types:
T: f32, f16, bf16.
Note: Inputs and outputs have the same data type denoted by T. For example, if input is f32 tensor, then all other tensors have f32 data type.
